As the season wears on and contender after contender fall out of the Heisman chase, Ohio State's Troy Smith seems all-but a lock for the award. But don't ask Smith to join the debate. He continues to say the right things as the No. 1 Buckeyes march on to their showdown with Michigan.[details]

The good: Riley is a versatile, naturally athletic lineman who can play any position on the offensive front. He started at guard and right tackle for Michigan. He has good balance and the lateral agility to mirror pass rushers and wall off defenders on running plays early in a game. He compensates for his athletic shortcomings with fine awareness and football intelligence. Riley uses his long arms to force rushers wide and utilizes his bulk to make it difficult for defenders to come off the edge.

The bad: Riley hasn't proved that he will take conditioning seriously and therefore occasionally wears down late in games. When he gets tired, his technique gets sloppy. He is still raw in certain elements of his technique and needs to learn some finer points of line play. He is not a natural knee bender and can lose leverage at times as a drive blocker. He occasionally loses his balance when he's asked to adjust to quick moves or secondary maneuvers, though he can maul an opponent once he locks onto him.

Outlook: Riley can be explosive, but he needs to improve his footwork to challenge for a starting role. Riley has the tools to emerge as a surprise, but he needs to improve his technique and strength. He's a good second-gamble with boom-or-bust potential.
